I am trying to book a domestic flight to Ronald Reagan Washington National Airport (DCA) at the end of this month. The itinerary I am looking is such that the flight will land at DCA at around 11:00 P.M, which I am assuming will be the last flight of the day. I'm moving into my new apartment the very next day, but I won't most likely have a place to stay overnight, so I am thinking of crashing at the airport in the lounge where the plane lands, and then waking up in the morning and catching a ride to my new place.
Is this allowed etc., especially at large airports located in large urban centers?
